Ventilation

MVHR: High performance heat recovery and ventilation. Full Heat recovery ventilation is installed into the new TCosy™ frame. Recovering 84% off the heat form internal heating sources and delivering fresh filtered all to all rooms. Incorporating the MVHR within the frame and penetrating only through the walls at high level minimizes internal disturbance and loss of internal space.
